BE 8.6 fails to Access M: on Exch

[heffy]

Backups were successfull for a week after upgrading to r3878 from r3808, but now failing.

BE v8.6 r3878 is running on our Exchange 2000 Server.
Licences installed: Server Edition, Agent for Exchange 2000 & Remote Agent for Windows 2000 Server.
The administrator account complys with:

I still recieve the following error!

Backup of "M: Exchange"
Backup set #7 on storage media #1
Backup set description: "Backup 0031 - 20020530"
Backup Type: FULL - Back Up Files - Reset Archive Bit
Backup started on 5/31/2002 at 2:37:52 AM.

What am I missing and what caused this to suddenly start failing?

Thanks!

It is not recommended to actually backup the M: drive. The absolute best advice is to remember this is a virtual drive and leave it alone. If you are doing an exchange aware backup, you do not need to back up your exchange folders or M: drive (not recommended). I also do a brick level backup so I can restore individual emails and boxes after my 30 retention is over.
